“我只在浏览器中收到一个错误，这是错误”：
意外的应用程序错误！元素类型无效：应为字符串（对于内置组件）或类/函数（对于复合组件），但得到：你可能忘记了从定义你的组件的文件中导出它，或者你可能混淆了默认的和命名的导入。检查Layout的render方法。

💿 嘿开发商👋
当应用抛出错误时，您可以通过提供自己的ErrorBoundary属性来提供比这更好的用户体验
“我一直在尝试在chatGPT中找到解决方案，但在我的浏览器中仍然出现同样的错误，我希望这里的任何人都能帮助我，给予我一个解决这个问题的方案”
“这是布局组件代码”：

import React from "react";
import { Outlet } from "react-router-dom";
import Footer from "../Footer/Footer";
import Navbar from "../Navbar/Navbar";

const Layout = () => {
  return (
    <div className="app">
      <Navbar />
      <Outlet />
      <Footer />
    </div>
  );
};

export default Layout;

这是我的App.js文件：

import React from "react";
import { createBrowserRouter, RouterProvider } from "react-router-dom";
import Home from "./pages/Home/Home";
import Product from "./pages/Product/Product";
import Products from "./pages/Products/Products";
import Layout from "./Components/Layout/Layout";

const router = createBrowserRouter([
  {
    path: "/",
    element: <Layout />,
    children: [
      {
        path: "/",
        element: <Home />,
      },
      {
        path: "/products/:id",
        element: <Products />,
      },
      {
        path: "/product/:id",
        element: <Product />,
      },
    ],
  },
]);

function App() {
  return <RouterProvider router={router} />;
}

export default App;

这是Navbar.js：

import React from 'react'

const Navbar = () => {
  return (
    <div>
      
    </div>
  )
}

export default Navbar

这里是footer.js：

import React from 'react'

function Footer() {
  return (
    <div>
      
    </div>
  )
}

export default Footer
